Title:
ModelCenter Integration with MagicDraw for MBSE
Abstract:
ModelCenter is an integration software that can be used to integrate 3rd party applications with models created in MagicDraw for systems engineering purposes. Connecting MBSE software to other applications allows versatile plug-ins to conduct system analysis, calculations, trade studies in formats compatible with a wide range of applications. The MBSE capabilities of MagicDraw are further expanded due to ModelCenter allowing external applications to work in parallel.

Title:
Subscale Testing and Simulation Development for Transitioning eVTOL
Abstract:
The Advanced Air Mobility (AAM) industry is a rapidly growing side of the aerospace industry that is made up of highly competitive companies working to develop electric vertical takeoff and landing (eVTOL) vehicles. In the interest of generating publicly available data on these eVTOL aircraft, the German Research Group at Georgia Tech has entered into a cooperative research agreement with NASA to develop a Research Aircraft for eVTOL Enabling TechNologies (RAVEN). The RAVEN project is a multi-year year effort including subscale vehicle development, high-fidelity simulation, ground testing, and eventual flight testing of a full-scale eVTOL research aircraft in the 1000-lb weight class.

Title:
Designing A Fluid Flow Heat Exchanger Utilizing LN2
Abstract:
One Design Criteria for the HAI project I currently work on is to reach a temperature of about negative forty degrees Fahrenheit. Since the air we run in has to be stored in standard conditions we needed a way to cool our air and fuel down to the desired test conditions while going through our rig. We decided to go with a design that incorporated multiple smaller lines running through one larger pipe in which the larger would have LN2 running through it while the smaller pipes would have air and fuel running through them. We decided upon this design as to maximize the cooling effect of the LN2. When considering the design we had to size the length based on the amount of heat we needed to transfer using heat transfer equations. Eventually we decided to utilize multiple heat exchangers as to be able to put them at different orientations at different points on our rig of so we did not have to change the overall design. After some iterations we successfully completed our heat exchanger system.

Title:
Optimization of Early-Stage Propeller Design Using OpenMDAO and BEMT
Abstract:
As part of a larger VLCROE Vertical Lift Optimization project centered on motor design for eVTOL aircraft, optimization modules were needed to couple vehicle trajectories with required performance variables at the rotor across the mission profile. Blade Element Momentum Theory, a method which combines rotor momentum theory with blade element theory, which looks at the sum of discrete airfoil elements which make up a blade, was used within an open-source framework for multidisciplinary optimization called OpenMDAO, to model the performance of a rotor given a provided blade geometry. Further optimization allowed for the determination of the best possible rotor design provided certain geometrical constraints. While tools like CFD are necessary for higher fidelity modelling and optimization of propellers, especially in more complex flows, these models should provide a tool for efficient preliminary rotor design optimization.Faculty Advisor:

Title:
Manufacturability and Robust Design of Beam Joints in the Cub-octahedron Voxel
Abstract:
This research investigates joint design for cub-octahedron voxel structures, emphasizing manufacturing feasibility and structural robustness, particularly for laser cutting applications. The problem statement underscores the necessity for designs enabling rapid manufacturing and easy assembly while ensuring structural integrity. Following an eight-step methodology, preliminary designs have been developed, meeting initial criteria but requiring further optimization. Notably, these designs offer simplicity in manufacturing and self-constraint, contrasting with existing larger-scale designs reliant on screws and tightened mechanisms. This research aims to refine joint designs for enhanced efficiency and performance within voxel-based structures, offering a valuable contribution to the field of structural engineering.
